To all whom 1'25 may concern: 7

Be it known that I, FREDERICK W.. LUscoins, of New Bedford, in thecounty of This invention relates to machines for insorting lacing hooksin shoe uppers, and is embodied in a machine including hook-settingmembers arranged and operated in a manner by which it is sought toimprove the quality of work performed, and to avoid accidental crushingor displacing of the lac-' ing hook whilev setting the same. To this endthe machine is provided with a lacing hook carrier and a setting member.

The machine also includes a flaring memher which acts upon the shank ofa hook to slightly flare the shank prior to the opera tion of theset-ting member, and which is provided with a punch for punching andfeeding the work.

In carrying out the invention, the'hook' carrier and the setting memberare arranged to slide toward and from each other in fixed bearings, andthe-flaring member is arranged to slide 'in movable bearings and isactuated to first puncture and then feed the work. In-operation theflaring member in feedingthe work moves to a position in the line of thesetting member, and remains in such position during a movement of thelIOOlCCaI'IIGI which inserts the shank of the hook in the work andslightly flares the shank against the flaring member. The

carrier then remains stationary -while the fla ring member recedesandmoves laterally,

be displaced after having once-been engaged by the punch until after thecompletion of the setting operation.

The invention also includes means forvarying the length of the feedingstrokes in conformity with Work of different sizes, and

an adjustable gage for the work is provided and connected to the feedadjusting means whereby the gage may be auton'iatical y adjusted whenthe feeding means is adjusted. By reason of combining the gage with thefeeding means in this manner, accuracy is insured in setting the hooksin one flap of the work in the same relative positions as those in theopposite flap.

Other features of novelty and advantage are hereinafter described, andare illustrated upon the accompanying drawings.

The same reference characters indicate the same parts wherever theyoccur.

A frame in which the various devices and actuating mechanism are mountedis indicated at 30, and is formed with bearings 31 for a prime powershaft 32. The frame is formed with an overhanging front portion providedwith fixed bearings 33 for a plunger 34. A setting member 35 is aflixedat the lower end of the plunger 34. The lower part of the frame istformed with a cylindrical housing 36, and with fixed bearings 37 for a,slidingplunger 38. The bearings .37 are in line with the upper bearings33,

-' and the plunger 34 and plunger 38 are movable toward and from eachother. The upper end of the plunger 38 is provided with 'a pivotedcarrier 40 mounted upon a pivot stud 39. The carrier 40 receives, thelacing hooks a: one at a time, and transfers them from a lower plane tothe work a which is supported upon a feed table 41.

The means for reciprocating the plunger 34 is shown by Fig. 9 andincludes a cam. 42 on the shaft 32, a yoke 43 cotiperating with the cam,an arm 44 aflixed upon a rockshaft 45, and a connecting rod including aturn-buckle 46 connecting the yoke and the arm 44. The rock-shaft ismounted in hearings in the frame 30,. and has affixed at its forward enda forked arm 47 which embraces a sliding block 48 pivotally connected tothe plunger 34. The shape of the cam 42 is such as to provide a dwell oftheplunger at each extreme of its movement.

Means for actuating the plunger 38 is shownby Figs. 1 and 2, andincludes'a cam 49 affixed upon the shaft 32, and arranged within thehousing 36. The cam cooperates with a roll 50 attached to a block 51onthe plunger, and the action of the cam is such as to impart anirregular motion to'th'e plunger, as hereinafter explained. v j

The flaring member is indicated at 52, and is formed with a centralprojection 53 which is employed to punch and feed the work. The member52 is affixed at the lower end of a plunger 54 which is mounted to slidein bearings 55 on a feed carriage 56. The feed carriage is formed with ahollow sleeve 57 shown by Figs. 10 and 24, and the sleeve is arranged ina bearing 58 formed on the frame 30. The lower end of the sleeve isprovided with an arm 59 which is formed with. a groove 60, and which isengaged by means hereinafter described for oscillating it toimpartfeeding motion to the carriage. lhe'motion of the carriage is suchas to move the member 52 to and from the line of the settingmember 35and the feeding stroke may be increased or decreased by ad justing theactuating means as hereinafter described.

The plunger 54 which carries the flaring member and punch isreciprocated in its bearings 55 toward and from the feed table by togglelinks 61 and 62 (see Fig. 2). The link 61'is pivoted at 63 to a portionof the feed carriage, and the link 62 is pivoted at 64 vto-a block orcollar affixed to the plunger 54. The two links are joined by a pivotstud 65 which passes through one end of alink orconnecting rod 66 theother end of Which is pivotally connected to a bell crank 67. Theconnecting link 66 is here shown as including a turn-buckle 68 by whichit may be adjusted. The bell crank 67 is pivoted at, 69 to the feedcarriage '56, and it has an arm which is pivoted at 70 to the upper endof a plunger 71 which extends through the hollow sleeve 57. The lowerend of the plunger 71 carries aswiveled yoke 72 which embraces theshaft32 and which is provided witha cam roll 73 cooperating with a cam 74' onthe shaft. The movement imparted by the cam is such as to move the ivotstud 65 which connects the toggle links rom'the position shown by Fig. 8to a position on the other side of a line intersecting the pivots 63and'64. As a result of moving the stud 65 in this manner the punch isinsorted in the work and its pressure upon the feed table is slightlyrelieved when'the stud 65 moves beyond the line of the pivots and 64.'The purpose of so moving the punch to first punch the work and thenrelieve the pressure upon the feed table is to permit a relatively freefeeding movementof the carriage 56 without exerting undue friction uponthe feed table.

The lacing hooks are fed from a reservoir 75 to the upper end of a race76 upon which they slideto a position atthe rear of the setting member35. The lower end of eel the race 76is above and at the rear of thepoint where the hooks are placed upon the carrier 40 and theyaretransferred from the race 76 to the carrier by a supplementalrace 76('see Fig. 4). The foremost hook at the lower end of the race 76 isengaged by a remember 77 which is actuated and leasing I ftu'lne torelease the hooks one at a time, aridt'o; retain all but, the foremosthook.

' race.

The member 77 is formed with a finger 7 8,

and with a blade 79, and is affixed upon a rock stud 80 which isoscillated to effect single feeding of the hooks. The finger 78 moves toand from a position in alinement with the lower end of the race and isadapted to receive the hook portion of a lacing hook, as shown by Fig.4. When the releasing member is oscillated in the direction of the arrowin Fig. 4, the finger 78 is retracted from the lacing hook, thuspermitting the hook to slide upon the supplemental race 7 6 and theblade'7 9 is simultaneously moved transversely across the end of therace 76, and thereby closes the mouth of the The race 7 6 terminates ina horiio-ntal portion above which is a spring actuated detent 81 mountedin a socket in the feed table, as shown byFigs. 4 and 23. The detent ismovable transversely of the race 76' and normally stands in a positionwhere it is adapted to engage and st'op'a hook,- as

shown by Fig. 6. From this position, the hook ispositively advanced by anose 82 on the forward end ofaplunger 83 which is reciprocated towardand from the carrier 40.

The mechanism for actuatingthe hook releasing member 77 is illustratedby Fig. 3, and includes a .cam 84 aflixed upon the rockshaft 45, and acam lever 86 pivoted at 86. One end of the lever is held against the camby a spring 87, and the other end of the lever is provided with apivoted hook finger 88 which is adapted to engage a complemental hookfinger 89 aflixed upon the rock stud 80 which carries the member 77. Thefinger 89 is normally held against a stop 90 r by a spring 91 and thepivoted hook 88 is position shown by Fig.4 by reason of its normallyheld against the finger 89 by a spring 92. The hook 88 is so actuated asto overreach the finger 89 and then toretract the latter to effect therelease of-a lacing hook. The hook 88 is then disengaged from the finger89 and the latter is restored to the spring 91. I

The mechanism tor-reciprocating the feed plunger 83 is shown by Figs. 14and 15, and includes a cam 93 affixed upon. the shaft 32.

A cam lever 94 pivoted at '95 is provided with a cam roll 96 whichis'held against the cam by a spring 97. The free end of the le.- ver 94is attached to a link 98 whose forward end is pivoted upon a stud 99extending through a slot 100 in the frame '30. The

stud 99 is affixed in the plunger 83 andoperative connection is therebycompletedbetween the cam lever and the plunger. When the plunger isprojected forwardly for the 4 purpose of feeding a hook, the nose 82.en-

gages the hook,

as shown by Fig. 5, and

, moves the open portion of the'hook over a receiving part of thecarrier 40. The hook in moving from the position shown by Fig.

6 to the, positio shown by Fig. 5 slightly displaces the spr ng detent81 which immediately springs back into the path of a succeeding hook.

The hook carrier 40 is pivotally connected to a second plunger 40through the medium of a pivot stud 39. The plunger 40 is positivelyactuated, as hereinafter described, for the purpose of retracting thecarrier to the position shown by Fig. 7 at the completion of a settingoperation. The plunger eX- tends downwardly through hearings in thehousing 36 and is provided with a stud 101 which is connected to aspring 102, normally raising the studagainst the free end of a swingingarm 103. The arm is aflixed at one end of a rock-shaft 104 which ismount-' ed in bearings in the frame 30, and which is provided with a camarm 105 at the free end of which is a cam roll 106 cooperating with acam 1.07 on the shaft 32 (see Figs. 1 and 11). It will be observed thatthe spring 102 tends to continuously raise the plunger 40, and that: theposition of the stud .101 is determined by the arm 103 which is actuatedby the cam 107. The cam 107 and the cam 49 which actuates the plunger 38are so related as to permit the two plungers'to rise in unison to insertthe hook in the work.

While the plunger 40. is held elevated the plunger 38 is depressed everso'slightly by the portion 49 of the cam 49. This movement separates thecarrier and setting member sufficiently to relieve all pressure upon isdeadapted to receive another hook w. A stop pin 108 is arranged in thehead of the plunger 38 to limit the rocking of the carrier 40, i asshown by Figs. 4 and 5.

When the carrier is raised to transfer a hook, the hook engages theyielding member 109, shown by Figs. 23, 24, and 25. The member 109 ispivoted at110 and is normally held in position to engage the hook by aspring 111, and is provided for the purpose of preventing the hook fromleaving the carrier while the carrier is inmotion.

' The feed carriage 56 is oscillated ,by-a cam 112 shown in F g. 24. Thecam is affixed upon theshaft- 32 and cooperates with a cam roll 113 atthe free end of an'arm 114. pivoted upon a stud 115. The arm 114 isformed with asecond'arm 116, which is provided witha slot 117 in whichis arranged a sliding block 118.. A stud 119 extion of the pointer 123cooperating with the,

tends through the block- 118, through a link 120 and through a similarblock which occupies the groove 60 in the arm 59 attached to the hollowsleeve of the feed carriage. lVhen the cam arm 114 is oscillated,movement is imparted to the arm 59 and the feed carriage is thusoscillated to move the punch to and from the line of the setting member.The link 120 3 connected to a stud 121 car ried by a hand lever 122, bywhich the stud 119 may be shifted relatively .to the arms 116 and 59 forthe purpose of increasing or decreasing the length of the feedingstrokeof the carriage. The hand lever 122 may be provided with a pointer 123and the machine may be provided with a gage plate 124 having an index125 adapted to coiiperate with the pointer 123 for the purpose ofdetermining the desired adjustment of the feed regulating mechanism. Thegage plate 124 may be provided with notches 126, as shown by Fig. 2, andthe hand lever may be provided with a spring actuated latch 127 adaptedto enter the notches 126 and lock the lever in the position to which itis inoved.

Figs. 1 and 24 include a work gage 128 which is adapted to be engaged bythe work for determining the initial position of the Work with relationto the feeding'and hooksetting devices. In practice, the right hand sideof a shoe quarter is provided with hooks before the hooks are insertedin the lefthand side of the quarter. The'quarter is placed upon the feedtable in the position indicated by dotted lines in Fig. 24, with the topedge lying in the angle of the gage 128; The gage thus determines theposition of the lowermost hook, that is, the hook which is farthest fromthe top edge of the quarter. After the full number of hooks has been setin this side of the quarter, the quarter is in verted and the left handside is placed upon the feed table in the reverse position, that is, insuch position as to insert the first hook at the top so that the quarterwill be fed from the top toward the bottom. The operator in determiningthe position of the first hook in the left hand side of the quarter maybe guided by observing the relative osition of the top hooliv oftheright hand side of the quarter, and the work-feedingmecha 'nism willthereafter determine the correct positions of the succeeding hooks.

The gage 128 is adjustable, and is connected to the feed regulatingmechanism by means which automatically ad'ust the gagein accordance withthe spacing of the hooks,

and therefore in accordance with the posiindex 125. The gage is hereshown as affixed at one end of a rod 129 which is mounted to slide in abearing 130. The bearin is afforded by the head of a stud 131 pivoted ina bracket 132. A collar 133- affixed to the rod 129 is piautsllyconnected with an arm 134 by means ofla link 135. The arm 134 is tightlyclamped on a rock stud 136 which is provided with a second arm 137. Thearm 137 is formed with a slot 138 which is occupied by an adjustableclamping stud 139. The stud 139 extends through one end of a link 140 ofwhich the other'end is pivoted upon the stud 121. By this means, thegage 128 is'mo red by the hand lever 122 in accordance with the feedregulating mechanism.

The Work is held upon the feed table by a presser-foot 141 which isclamped on a stud 142 carried by a vertically movable rod 142 The rod142 is mounted in bearings 143 in the frame 30, and is provided with acollar 144, and with a helical spring 145 compressed between the collarand one of the bearings 143. The force of the spring tends to hold. thepresser-foot downwardly upon the feed table and the presser-foot isperi-, odically elevated by a cam 146 on the shaft 32 (see Figs. 12 and13). The cam cooperates with a cam roll 147 at tlie free end of an arm148. The arm is aflixed upon one end of a rock-shaft 149 mounted in abearing 150. The other end of the rock-shaft carries an arm 151 at thefree end of which is a roll 152 which is adapted to engage an inclinedface of a finger 153 formed upon the collar .144. These elementstransmit movement from the cam 146 to the presserfoot for lifting theresser-foot.

The presser-foot may be manually raised when it is desired to insert'orremove the work. For this purpose a lifting member 154 is provided, asshown by Figs. 1 and 2. The lifter 154 is in the form of a lever and ispivoted at 155', and is connected to a rod 156 which may be providedwith a treadle, not shown. r

For the purpose of guiding the work as it. is fed along the feed table,the table is rovided with a fixed guide 157, as shown y Figs. 3 and 4.
